SOFTWARE METAPAPER pycalphad: CALPHAD-based Computational Thermodynamics in Python Richard Otis and Zi-Kui Liu Department of Materials Science and Engineering, Pennsylvania State University,

[1]. A very limited rst version of the OpenCalphad (OC) software was released The strength of the CALPHAD method is that the descriptions of the constituent sub-systems can be combined to describe a multi-component system. Equilibrium calculations. The second crucial factor is the availability of computer software for calculating equilibria and various kinds of diagrams and databases with the stored assessed information. CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) aims to promote computational thermodynamics through development of models to represent thermodynamic properties for various phases which permit prediction of properties of multicomponent systems from those of binary and ternary subsystems, critical assessment of data and their All of the CALPHAD-type software tools use methods like the two-step method of Hillert 41 or the one step method Lukas et al.

OpenCalphad - V 5.0. Includes Main Program Source Code, User Guide, Software Documentation and Test Files. OpenCalphad (OC) is an informal international collaboration of scientists and researchers interested in the development of high quality software and databases for thermodynamic calculations using the CALPHAD (CALculation of PHAse Diagrams) method.The OC project was initiated by Suzana G. Fries as part of the Sapiens project at ICAMS (International Calphad software for thermodynamic applications, simply called Open Calphad, OC, to provide a free software for multicomponent equilibrium calculations. In this presentation I will provide an short description of the OC Application Software Interface (OCASI) and some examples how this can be used. TMS2016 applications CALPHAD stands for CALculation of PHAse Diagrams, a methodology introduced in 1970 by Larry Kaufman. An equilibrium phase diagram is usually a diagram with axes for temperature and composition of a chemical system.

pycalphad is a free and open-source Python library for designing thermodynamic models, calculating phase diagrams and investigating phase equilibria within the CALPHAD method. It provides routines for reading Thermo-Calc TDB files and for solving the multi-component, multi-phase Gibbs energy minimization problem.

For simulations it can calculate equilibria in parallel using OpenMP. Calphad is a method of CALculating PHAse diagrams.

4 Sep 2015 of the CALPHAD (CALculation of PHAse Diagrams) method are commercial software applications like MICRESS [38] or TC-PRISMA [42].

CALPHAD Applications in Materials Design, Advanced Manufacturing, Recycling, Disposal, CALPHAD Applications in industrial processes (energy production, joining and soldering, ) 2015-01-17 · CALPHAD calculations can be carried out as stand-alone calculations or can be carried out coupled with simulation codes using the result from these calculations as input. A number of CALPHAD software are available for the calculation of properties of multicomponent systems, and the majority are commercial products. During the calculations with CALPHAD software packages like FactSage [36], OpenCalphad [37], Pandat [38], Pycalphad [39] and Thermo-Calc [40], this part is automatically added to the calculated CALPHAD descriptions can be extrapolated also outside the equilibrium state and thus, when they are included in any calculation or simulation, provide information about values and gradients of the thermodynamic properties in space and time outside the range of stability of a phase. 2020-11-02 · Thermo-Calc is a powerful software package used to perform thermodynamic and phase diagram calculations for multi-component systems of practical importance.

Our CALPHAD software and databases are designed to be flexible, so you only purchase the tools you need.

Figure 1. Our databases are developed using a process called a CALPHAD Assessment, and the video explains what a CALPHAD assessment is and walks you step-by-step through the process. The assessment involves searching and evaluating all of the literature data, defining a Gibbs energy model depending on its crystal or chemical structure, fitting the model to the data and more.
